[0002] An atomizer is a device used to heat an aerosol matrix to atomize it into an aerosol. Existing atomizers typically have a single heating element inside. Single-element atomizers have a limited heating area, resulting in long preheating times when starting up electronic atomization devices. Furthermore, the concentrated heating of a single element can easily lead to coil burning. Utility Model Content

[0003] The purpose of this application is to provide an atomizer to solve the technical problem of relatively small heating area in existing single-core atomizers.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: The first aspect of this application provides an atomizer, comprising:

[0005] Liquid storage tank;

[0006] Liquid-guiding cotton is supported inside the liquid storage chamber, and a liquid storage space is formed between the liquid storage chamber and the liquid-guiding cotton. There are two or more installation channels that penetrate the liquid-guiding cotton.

[0012] In some implementations, the atomizer also includes an upper seal, a connecting cylinder portion formed on the inner side of the liquid storage chamber, and one end of the atomizing outer cover is sealed to the connecting cylinder portion through the upper seal.

[0013] In some implementations, an air-guiding gap is formed between the atomizing outer cover and the liquid-guiding cotton.

[0014] In some implementations, the atomizer also includes a base support and a base sealing part. The base sealing part is connected to the base support and is sealed to the inner side of the liquid storage chamber. An air guide chamber is formed between the base support and the base sealing part. One end of the atomizing core is supported on the base sealing part and is connected to the air guide chamber inside the atomizing core. An opening connected to the air guide chamber is formed on the base support.

[0015] In some implementations, the atomizer also includes a first electrode and a second electrode. Each atomizing core includes a first pin and a second pin. The first pin of each atomizing core is connected to the first electrode, and the second pin of each atomizing core is connected to the second electrode. The distance from the axis of each atomizing core to the axis of the first electrode is the same, and the distance from the axis of each atomizing core to the axis of the second electrode is the same.

[0016] In some implementations, there are multiple openings, which are symmetrically arranged on the base support, and the axis of symmetry of the multiple openings is perpendicular to the distribution direction of the atomizing core on the liquid guiding cotton.

[0017] In some implementations, there are two atomizing cores, which are symmetrically arranged inside the liquid-guiding cotton.

[0020] In some implementations, the liquid storage tank includes a main body and a suction nozzle. The suction nozzle is located at one end of the main body, and the interior of the suction nozzle is connected to each installation channel. The installation channels are symmetrically arranged on the liquid guiding cotton, and the axis of the suction nozzle is collinear with the axis of the liquid guiding cotton.

[0021] A second aspect of this application provides an electronic atomizing device, including a battery rod and an atomizer as provided in any of the above technical solutions, wherein the atomizer is disposed at one end of the battery rod and the two are connected.

[0048] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the structure of the atomizer 100 provided in some embodiments of this application. Figure 2 This is a cross-sectional schematic diagram of an atomizer 100 provided in some embodiments of this application. Figure 3 This is an exploded view of the atomizer 100 provided in some embodiments of this application. For ease of description, please refer to... Figure 1 In this embodiment of the application, the width direction of the atomizer 100 is defined as the X-axis direction, the thickness direction of the atomizer 100 is defined as the Y-axis direction, and the length direction of the atomizer 100 is defined as the Z-axis direction, wherein the X-axis direction, the Y-axis direction, and the Z-axis direction are mutually perpendicular.

[0049] Please see Figure 2 The atomizer 100 provided in this embodiment includes a liquid storage chamber 10, a liquid-guiding cotton 20, and an atomizing core 30, wherein the liquid-guiding cotton 20 and the atomizing core 30 are disposed within the liquid storage chamber 10. Please refer to... Figure 1 A suction nozzle 12 is formed on the liquid storage tank 10, and the user can suck air through the suction nozzle 12 when using it.

[0050] Please see Figure 2 The liquid-guiding cotton 20 is supported within the liquid storage chamber 10, forming a liquid storage space 40 between the liquid storage chamber 10 and the liquid-guiding cotton 20. The liquid storage space 40 is used to place the aerosol matrix. Please refer to... Figure 2 and Figure 3 The liquid-guiding cotton 20 has two or more installation channels 21 that penetrate the liquid-guiding cotton 20, and one end of each installation channel 21 is connected to the suction nozzle 12.

[0051] Please see Figure 2 Each installation channel 21 is equipped with an atomizing core 30, that is, there are two or more atomizing cores 30 and each atomizing core 30 corresponds to an installation channel 21. Each atomizing core 30 is installed in its corresponding installation channel 21. The aerosol matrix in the liquid storage space 40 can penetrate into the atomizing core 30 through the liquid guiding cotton 20.

[0052] In one example, the liquid-guiding cotton 20 has two installation channels 21, and there are two atomizing cores 30, with each atomizing core 30 inserted into its corresponding installation channel 21; or, in other examples, the liquid-guiding cotton 20 has three or more installation channels 21, and there are three or more atomizing cores 30, with each atomizing core 30 installed in its corresponding installation channel 21.

[0053] In one example, all atomizer cores 30 have the same structure; or, in other examples, the structures of each atomizer core 30 may differ.

[0054] In some examples, the mounting channels 21 have the same diameter to accommodate atomizer cores 30 of the same size; or, in other examples, the mounting channels 21 have different diameters to accommodate atomizer cores 30 of different sizes.

[0055] In this embodiment, the atomizing core 30 includes a heating element, which may be a heating wire or a heating mesh. The heating element can generate heat when an electric current is applied, that is, the atomizing core 30 can heat the aerosol matrix that has penetrated into the atomizing core 30 to make it evaporate. When the user inhales through the mouthpiece of the liquid storage chamber 10, causing airflow inside the atomizing core 30, the evaporated aerosol matrix can form mist under the condensation effect of the airflow. Finally, the mist can flow to the mouthpiece with the airflow.

[0056] In existing related technologies, a single heating element is usually installed inside the atomizer. The heating area of ​​a single-element atomizer is limited, which results in a long preheating time when the electronic atomizing device is started. In addition, the concentrated heating of a single element also makes it easy for the coil to burn (under the same power output, the smaller heating area will cause the heat to be concentrated on a unit area, which can easily cause the local temperature to be too high, thereby increasing the risk of coil burning).

[0057] In this embodiment, by including two or more atomizing coils 30 in the atomizer 100, the heating area can be increased compared to a single-coil atomizer, thereby reducing the preheating time during startup. Under the same power output, the larger heating area allows the heat to be distributed more evenly over a larger area, resulting in relatively lower heat per unit area. This reduces the likelihood of localized overheating leading to burnt coils, thus reducing the load on the atomizing coil 30 in the single-coil atomizer 100 and improving its lifespan. Furthermore, the simultaneous operation of two or more atomizing coils 30 allows for even carbon deposition, preventing rapid clogging of a single coil. This can handle high-concentration aerosol matrices, reduce burnt taste issues caused by poor wicking, and increase atomization output.

[0058] In some embodiments, see Figure 2 There are two atomizing cores 30, which are symmetrically arranged inside the liquid guiding cotton 20.

[0059] In some examples, the transverse surface of the outer circumferential side of the fluid-wicking cotton 20 (parallel to) Figure 3 The XOY plane is shaped like a racetrack, with two 30mm atomizing cores along its length. Figure 3 The direction of the X-axis is set sequentially.

[0060] In this embodiment, the atomizing cores 30 are symmetrically arranged inside the liquid-guiding cotton 20 to ensure that the amount of aerosol matrix absorbed by the atomizing cores 30 is the same, thus avoiding the situation where some atomizing cores 30 burn out. In addition, the symmetrical layout facilitates the gripping and positioning of the robotic arm during the assembly of the atomizer 100, thereby improving the assembly efficiency.

[0061] In some embodiments, the liquid storage tank 10 includes a transparent area or a semi-transparent area.

[0062] In some examples, the liquid storage tank 10 is made of a transparent or semi-transparent material; or, in the gas example, some areas of the liquid storage tank 10 are made of a transparent or semi-transparent material, while the remaining areas are made of a non-transparent material.

[0063] In some examples, the material of the reservoir 10 includes polymethyl methacrylate, polypropylene, or polyvinyl chloride, etc.

[0064] In this embodiment of the application, the liquid storage tank 10 is provided with a transparent area or a semi-transparent area so that the content of the aerosol matrix inside the liquid storage tank 10 can be observed through the transparent area or the semi-transparent area.

[0065] In some embodiments, see Figure 1 and Figure 2 The liquid storage chamber 10 includes a main body 11 and a suction nozzle 12. The suction nozzle 12 is located at one end of the main body 11, and the installation channel 21 is symmetrically arranged on the liquid guiding cotton 20. The axis of the suction nozzle 12 is collinear with the axis of the installation channel 21.

[0066] In some examples, the axis of the nozzle 12, the axis of the main body 11, and the axis of the mounting channel 21 are collinear, and the two atomizing cores 30 are symmetrically arranged inside the liquid guiding cotton 20.

[0067] In this embodiment, the axis of the nozzle 12 is made collinear with the axis of the mounting channel 21 to facilitate the smooth flow of air through the atomizing core 30 to the nozzle 12, thereby improving the suction smoothness.

[0068] In some embodiments, see Figure 2 and Figure 3 The atomizer 100 also includes an atomizing cover 50, which is fitted over the liquid-guiding cotton 20 and connected to it. The atomizing cover 50 has a liquid inlet 51, and the liquid-guiding cotton 20 can be supported inside the liquid storage chamber 10 by the atomizing cover 50. Please refer to [link to relevant documentation]. Figure 2The diagram shows the liquid inlet 51 on the atomizing cover 50, through which the aerosol matrix in the liquid storage space 40 can flow to the liquid guide cotton 20.

[0069] In some examples, the atomizing cover 50 can be made of metal.

[0070] In some examples, the atomizing cover 50 is provided with a plurality of liquid inlet holes 51, which are arranged along the circumferential direction of the atomizing cover 50.

[0071] See some examples. Figure 4 The outer contour of the cross-section of the atomizing cover 50 (the cross-section parallel to the XOY plane) is racetrack-shaped, and the shape of the liquid guiding cotton 20 is the same as that of the atomizing cover 50, that is, the shapes of the two are matched.

[0072] In some examples, when the cross-section of the atomizing cover 50 and the liquid-guiding cotton 20 is racetrack-shaped, please refer to [reference needed]. Figure 2 The liquid-guiding cotton 20 contains two atomizing cores 30, which are located along the length of the atomizing outer cover 50. Figure 2 The interval setting is set along the X-axis.

[0073] In this embodiment, the atomizer 100 also includes an atomizing cover 50, which can provide support for the liquid-guiding cotton 20.

[0074] In some embodiments, the atomizing cover 50 is provided with liquid inlet holes 51 on two opposite sides along the first direction, and the liquid inlet holes 51 distributed along the first direction are symmetrically arranged on the atomizing cover 50. For ease of description, the liquid inlet holes 51 distributed along the first direction are referred to as first liquid inlet holes 511. Please refer to [link to relevant documentation]. Figure 4 This indicates the direction along the first direction (i.e. Figure 4 The first liquid inlet 511 is symmetrically arranged in the X-axis direction; or, in other embodiments, the atomizing cover 50 has liquid inlet 51 on two opposite sides along the second direction, and the liquid inlet 51 distributed along the second direction are symmetrically arranged on the atomizing cover 50. For ease of description, the liquid inlet 51 opposite along the second direction is referred to as the second liquid inlet 512. Please refer to [link to relevant documentation]. Figure 4 This indicates the direction along the second direction (i.e. Figure 4 The second liquid inlet 512 is symmetrically arranged in the Y-axis direction; or, in other embodiments, please refer to Figure 4 The atomizing cover 50 is provided with a first liquid inlet 511 symmetrically arranged along a first direction and a second liquid inlet 512 symmetrically arranged along a second direction.

[0075] See some examples. Figure 4The number of first liquid inlet holes 511 is two, and the two first liquid inlet holes 511 are symmetrically arranged along the first direction; or, in other examples, the number of first liquid inlet holes 511 is an even number other than two.

[0076] See some examples. Figure 4 The number of second liquid inlet holes 512 is two, and the two second liquid inlet holes 512 are symmetrically arranged along the second direction; or, in other examples, the number of second liquid inlet holes 512 is an even number other than two.

[0077] See some examples. Figure 2 The liquid inlet 51 on the atomizing cover 50 is located away from the nozzle 12 on the liquid storage tank 10.

[0078] Please see Figure 4 The atomizing cover 50 is provided with a first liquid inlet hole 511 and a second liquid inlet hole 512. That is, the atomizing cover 50 adopts a front-to-back symmetrical and left-to-right symmetrical oil inlet method, which is conducive to ensuring that the liquid storage space 40 has oil inlet in all four directions of the liquid guide cotton 20, thereby ensuring that the atomizing core 30 in the liquid guide cotton 20 can draw in the aerosol matrix.

[0079] In this application, by symmetrically setting the liquid inlet holes 51 on the atomizing cover 50, the amount of aerosol matrix absorbed by the atomizing core 30 is the same when the atomizing core 30 is symmetrically set on the liquid guiding cotton 20. This avoids the situation where individual atomizing cores 30 burn out, improves the service life of the atomizer 100, and also helps to ensure that the atomization efficiency of each atomizer 100 is the same.

[0080] In some embodiments, an air-guiding gap is formed between the atomizing outer cover 50 and the liquid-guiding cotton 20.

[0081] Please see Figure 2 As the aerosol matrix within the liquid storage space 40 gradually decreases, the air pressure within the liquid storage space 40 decreases, which is detrimental to the penetration of the aerosol matrix within the liquid storage space 40 into the atomizing core 30. Therefore, in this embodiment, an air-guiding gap is formed between the atomizing outer cover 50 and the liquid-guiding cotton 20. External gas can flow into the interior of the liquid storage space 40 through the suction nozzle 12 and the air-guiding gap, which helps to increase the air pressure within the liquid storage space 40, thereby allowing the aerosol matrix within the liquid storage space 40 to smoothly penetrate into the atomizing core 30.

[0082] It is worth noting that there is a gas-guiding gap between the atomizing outer cover 50 and the liquid-guiding cotton 20. The size of the gap is not small. However, it is necessary to ensure that the liquid storage space 40 and the nozzle part 12 can be connected, while also ensuring that the aerosol matrix in the liquid storage space 40 does not leak through the gas-guiding gap due to the large size of the gap.

[0083] In some embodiments, see Figure 2 and Figure 3 The atomizer 100 also includes an upper seal 60, and a connecting cylinder portion 13 is formed on the inner side of the liquid storage chamber 10. One end of the atomizing outer cover 50 is sealed to the connecting cylinder portion 13 through the upper seal 60.

[0084] See some examples. Figure 2 The liquid storage tank 10 includes a main body 11, a suction nozzle 12, and a connecting cylinder 13. The suction nozzle 12 is disposed outside the main body 11 and connected to one end of the main body 11. The connecting cylinder 13 is disposed inside the main body 11 and connected to the main body 11. The suction nozzle 12 is disposed above the connecting cylinder 13 and the two are internally connected.

[0085] In some examples, the liquid storage tank 10 is a one-piece molded structure.

[0086] In some examples, the transverse surface of the outer circumferential side of the nozzle portion 12 (parallel to) Figure 3 The XOY plane is shaped like a racetrack; and / or, the transverse surface of the inner circumferential side of the nozzle 12 is parallel to... Figure 3 The plane of XOY is shaped like a racetrack.

[0087] In some examples, the transverse surface of the outer circumferential side of the connecting cylinder 13 (parallel to) Figure 2 The plane of the XOY section is shaped like a racetrack; and / or, the transverse street surface on the inner circumferential side of the connecting cylinder 13 (parallel to) Figure 2 The plane of XOY is shaped like a racetrack.

[0088] See some examples. Figure 2 The upper sealing element 60 is sleeved on the outer circumferential side of the connecting cylinder portion 13; the atomizing outer cover 50 is sleeved on the outer circumferential side of the upper sealing element 60, or, please refer to Figure 2 One end of the atomizing cover 50 is inserted into the upper seal 60. Alternatively, in other examples, the upper seal 60 is disposed on the inner circumferential side of the connecting cylinder 13; the atomizing cover 50 is disposed on the inner circumferential side of the upper seal 60, or one end of the atomizing cover 50 is inserted into the upper seal 60. Alternatively, in other examples, the free end of the connecting cylinder 13 is inserted into the upper seal 60, and the atomizing cover 50 is sleeved on the outer circumferential side of the upper seal 60, or the atomizing cover 50 is disposed on the inner circumferential side of the upper seal 60.

[0089] In this embodiment, by setting one end of the atomizing cover 50 to be sealed with the connecting cylinder 13 through the upper sealing member 60, the structure of the atomizer 100 can be simplified while one end of the atomizing cover 50 is supported on the liquid storage tank 10.

[0090] In some embodiments, see Figure 2 and Figure 3The atomizer 100 also includes a base 70, which is inserted into the liquid storage tank 10 from the end opposite to the mouthpiece 12. The base 70 includes a base support 71 and a base sealing part 72. The base sealing part 72 is connected to the base support 71 and seals against the inner side of the liquid storage tank 10.

[0091] In one example, the base support 71 is inserted into the liquid storage tank 10 and the two are connected by a snap-fit.

[0092] Please see Figure 2 An air guide cavity 73 is formed between the base support part 71 and the base sealing part 72. One end of the atomizing core 30 is supported on the base sealing part 72 and is connected to the interior of the atomizing core 30 and the air guide cavity 73. An opening 715 is formed on the base support part 71 that is connected to the air guide cavity 73. External air can enter the air guide cavity 73 through the opening 715 and flow to the interior of the atomizing core 30 through the air guide cavity 73.

[0093] See some examples. Figure 3 and Figure 5 A sealing through hole 721 is provided on the base sealing part 72, and the atomizing core 30 is inserted into the corresponding sealing through hole 721. The atomizing core 30 and the base sealing part 72 are tightly fitted together.

[0094] See some examples. Figure 3 A first annular slot 722 is formed on the base sealing part 72. One end of the atomizing cover 50 can be inserted into the base sealing part 72 through the first annular slot 722, and the base sealing part 72 and the atomizing cover 50 are sealed together.

[0095] See some examples. Figure 3 An annular protrusion 724 is formed on the circumferential side of the base sealing part 72, and the annular protrusion 724 is used to seal with the inner side of the liquid storage tank 10.

[0096] See some examples. Figure 5 A second annular slot 723 is formed on the base sealing portion 72, and the second annular slot 723 faces the base support portion 71. Please refer to [link / reference]. Figure 3 and Figure 6 The base support portion 71 has an annular insertion end 711, which is inserted into the second annular slot 723, and the base sealing portion 72 is sealed to the base support portion 71.

[0097] In this embodiment, by providing a base 70 including a base support 71 and a base sealing 72, an air passage communicating with the interior of the atomizing core 30 can be formed on the base 70, which also helps to simplify the structure of the atomizer 100.

[0098] In some embodiments, see Figure 3 Each atomizing core 30 includes a first pin 31 and a second pin 32. The atomizer 100 also includes two electrodes 80, which are a first electrode 81 and a second electrode 82, respectively. The first pin 31 of each atomizing core 30 is connected to the first electrode 81, and the second pin 32 of each atomizing core 30 is connected to the second electrode 82. The distance from the axis of each atomizing core 30 to the axis of the first electrode 81 is the same, and the distance from the axis of each atomizing core 30 to the axis of the second electrode 82 is the same.

[0099] In one example, the atomizer 100 includes two atomizing coils 30. A first lead 31 of the atomizing coil 30 is close to a first electrode 81, and a second lead 32 of the atomizing coil 30 is also close to the first electrode 81. This facilitates the bending of the first lead 31 to connect with the first electrode 81, and the bending of the second lead 32 to connect with the second electrode 82. It is worth noting that... Figure 3 The first pin 31 and the second pin 32 shown in the diagram are in an unbent state.

[0100] In this embodiment, by setting the distance from the axis of each atomizing core 30 to the axis of the first electrode 81 to be the same, and the distance from the axis of each atomizing core 30 to the axis of the second electrode 82 to be the same, the length of each first pin 31 is the same when the first pin 31 of each atomizing core 30 is connected to the first electrode 81, and the length of each second pin 32 is the same when the second pin 32 of each atomizing core 30 is connected to the second electrode 82. This ensures that the resistance of each atomizing core 30 is the same, thus guaranteeing that the output power of each atomizing core 30 is the same.

[0101] In some embodiments, the first electrode 81 and the second electrode 82 are symmetrically arranged on the base support 71, and the axis of symmetry of the first electrode 81 and the second electrode 82 is parallel to the distribution direction of the atomizing core 30 on the liquid-guiding cotton 20.

[0102] In one example, see Figure 2 The atomizer 100 includes two atomizing coils 30, and the two atomizing coils 30 are along... Figure 2 The electrodes are arranged sequentially along the X-axis. The first electrode 81 and the second electrode 82 are symmetrically arranged on the base support 71, and the axes of symmetry of the first electrode 81 and the second electrode 82 are parallel to each other. Figure 3 The X-axis direction is parallel.

[0103] In one example, see Figure 6 The base support 71 is provided with a first electrode through hole 712 and a second electrode through hole 713. A first electrode 81 and a second electrode 82 are respectively inserted into the first electrode through hole 712 and the second electrode through hole 713. The first electrode through hole 712 and the second electrode through hole 713 are symmetrically arranged on the base support 71, and the axis of symmetry of the first electrode through hole 712 and the second electrode through hole 713 is along... Figure 6 In the X-axis direction.

[0104] In one example, see Figure 5 The base sealing part 72 is provided with a first electrode blind hole 725 and a second electrode blind hole 726. One end of the first electrode 81 and one end of the second electrode 82 are respectively inserted into the first electrode blind hole 725 and the second electrode blind hole 726. The first electrode 81 and the second electrode 82 are tightly fitted with the base sealing part 72.

[0105] In one example, the atomizer 100 includes two atomizing cores 30. The first pin 31 of the atomizing core 30 is close to the first electrode 81, and the second pin 32 of the atomizing core 30 is close to the second electrode 82. The first pin 31 of the atomizing core 30 passes through the base sealing part 72 and is bent to the first electrode blind hole 725 to connect with the first electrode 81. The second pin 32 of the atomizing core 30 passes through the base sealing part 72 and is bent to the second electrode blind hole 726 to connect with the second electrode 82.

[0106] In this embodiment, the first electrode 81 and the second electrode 82 are symmetrically arranged on the base support 71 to facilitate the connection of the pins of the bending atomizer 100 with the two electrodes 80.

[0107] In some embodiments, there are multiple openings 715, which are symmetrically arranged on the base support 71, and the axis of symmetry of the multiple openings 715 is perpendicular to the distribution direction of the atomizing core 30 on the liquid guiding cotton 20.

[0108] In one example, see Figure 2 The atomizer 100 includes two atomizing coils 30, and the two atomizing coils 30 are along... Figure 2 The holes are arranged sequentially along the X-axis, with the symmetry axis of the multiple 715 openings along... Figure 6 In the Y-axis direction.

[0109] In one example, the number of openings 715 is two, along... Figure 6 The opening 715 in the Y-axis direction is located near the middle of the base support 71.

[0110] In this embodiment, openings 715 are symmetrically arranged on the base support 71 to ensure that the airflow rate in the two atomizing cores 30 on the liquid guide cotton 20 is the same.

[0111] This application provides an electronic atomizing device, including a battery rod and an atomizer 100 provided in any of the above embodiments. The atomizer 100 is disposed at one end of the battery rod and the two are connected.

[0112] The details of the atomizer 100 have been described above and will not be repeated here. The handheld rod contains a battery and a circuit board. The handheld rod provides the necessary power to the electronic atomization device through the built-in battery so that it can work normally. The circuit board in the handheld rod is electrically connected to the electrode 80 in the atomizer 100. The working state of the atomizing coil 30 can be controlled through the circuit board.

[0113] In some examples, a receiving cavity is formed at one end of the battery rod, the atomizer 100 is inserted into the receiving cavity, and the gap between the battery rod and the atomizer 100 forms an air intake channel. When the mouthpiece 12 on the atomizer 100 is inhaled, external gas can flow through the air intake channel to the opening 715 at the bottom of the atomizer 100 and enter the interior of the atomizer 100 through the opening 715.

[0114] In some examples, a detection airway is also formed inside the battery rod. One end of the detection airway is connected to the opening 715 at the bottom of the atomizer 100, and the other end of the detection airway is equipped with an airflow detection device. When the mouthpiece 12 on the atomizer 100 is inhaled, the air in the detection airway is drawn in, which causes a negative pressure to be generated near the airflow detection device, thus triggering the airflow detection device.

[0115] In some examples, the atomizer 100 and the battery rod can be detachably connected, for example, by magnetic attraction or snap-fit ​​connection; in other examples, the atomizer 100 and the battery rod can be non-detachably connected.

[0116] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
